Hello All Timekeepers: First of all, let me say that this has been a very interesting discussion!
To summerize, it seems that our measurement of time will always be linked to the earth's rotation rate, because as daylength changes, so will our biological clocks. Consequentially, if we keep a 24 hour timescale in the future, then as the earth's rotation slows, the length of seconds, minutes and hours will increase because 24 hrs. will always equal one day (one rotation). Therefore, won't clock mechanisms have to evolve also, slowing down and running slower? Sundials would't have this problem, would they, since they measure the rotation rate directly?
